I like both, but, I think the UV's are not well done. It's because, how I see the textures, they're not properly tiled. Try by searching on youtube "blender to substance painter workflow", or "uv crop for texturing", stuff like that. I also suggest to start using Substance Painter to improve 3d quality, learn how to bake textures, you know the essentials but I think you can have a great gap if you want to.
Regards!
